HESI RN CAT Exit Exam 1
1. The nurse is caring for a client who has a chest tube in place following a pneumothorax. The nurse notes that there is continuous bubbling in the water seal chamber of the chest tube drainage system. What action should the nurse take?
- A. Check for kinks in the tubing
- B. Notify the healthcare provider
- C. Replace the chest tube drainage system
- D. Reinforce the chest tube dressing
Correct answer: B
Rationale: The correct action for the nurse to take when observing continuous bubbling in the water seal chamber of the chest tube drainage system is to notify the healthcare provider. Continuous bubbling indicates a possible air leak, and the healthcare provider needs to be informed to assess the situation and take appropriate actions. Checking for kinks in the tubing (Choice A) may be done initially but is not the priority when continuous bubbling is present. Replacing the chest tube drainage system (Choice C) and reinforcing the chest tube dressing (Choice D) are not immediate actions needed in response to continuous bubbling in the water seal chamber.
2. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?
- A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
- B. Administer a retention enema of Kayexalate.
- C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
- D. Administer a lidocaine bolus IV push.
Correct answer: B
Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.
3. A client who had a cerebral vascular accident (CVA) is paralyzed on the left side of the body and has developed a Stage II pressure ulcer on the left hip. Which nursing diagnosis describes this client's current health status?
- A. Risk for impaired tissue integrity related to impaired physical mobility
- B. Impaired skin integrity related to altered circulation and pressure
- C. Ineffective tissue perfusion related to inability to move self in bed
- D. Impaired physical mobility related to the left side paralysis
Correct answer: B
Rationale: The correct nursing diagnosis for this client is 'Impaired skin integrity related to altered circulation and pressure.' The client's Stage II pressure ulcer on the left hip is a clear indication of impaired skin integrity resulting from altered circulation and pressure due to immobility. Choice A is incorrect because the client already has a pressure ulcer, indicating an actual impairment rather than a risk. Choice C is incorrect as ineffective tissue perfusion is not the primary issue in this case. Choice D is incorrect as it focuses solely on the paralysis and not the actual skin integrity issue.
4. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?
- A. Blood glucose of 140 mg/dL
- B. White blood cell count of 8000/mm³
- C. Serum potassium of 3.8 mEq/L
- D. Serum calcium of 7.8 mg/dL
Correct answer: D
Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.
5. A client with an electrical burn on the forearm asks the nurse why there is no feeling of pain from the burn. During the dressing change, the nurse determines that the burn is dry, waxy, and white. What information should the nurse provide this client?
- A. The depth of tissue destruction is minor
- B. Pain is interrupted due to nerve compression
- C. The full thickness burn has destroyed the nerves
- D. Second-degree burns are not usually painful
Correct answer: C
Rationale: The correct answer is C: 'The full thickness burn has destroyed the nerves.' In full thickness burns, also known as third-degree burns, the nerve endings are destroyed, leading to a lack of pain sensation at the site of the burn. The description of the burn as dry, waxy, and white indicates a full thickness burn. Choices A, B, and D are incorrect because they do not explain the absence of pain in full thickness burns. Choice A is incorrect as a full-thickness burn involves significant tissue destruction. Choice B is incorrect because nerve compression would not explain the lack of pain in this context. Choice D is incorrect because second-degree burns, unlike full-thickness burns, are painful due to nerve endings being intact.
